i added an b&m fpr and gauge
to start with when i turn the car to the on location
it jumps to about 50lbs
and when i start the motor
it stays at about 59lbs
now no matter how high i adjust it or low i adjust it
it stays the same
this was all friday

now tonight i was gasing up i tried to adjusted it a lil bit
and when i got in the car the check engine light came on
i pulled the fuse the put it back in and still on

any ideas on either matter?

BTW i do have a walbro 255hp fuel pump
thanks
